Common questions
How do I create custom-sized bags from this tubing?
Simply cut the tubing to your desired length, insert your product, and use an impulse sealer to heat-seal both ends. This creates a completely sealed bag without requiring pre-fabricated inventory.
Why choose 6 mil thickness over thinner alternatives?
6 mil black poly provides heavy-duty protection with puncture resistance and complete light opacity, ideal for sensitive products. It handles rough handling in industrial environments while maintaining product integrity.
Can this tubing be sealed with any heat sealer?
Yes, standard impulse sealers work effectively with this low-density polyethylene. Check your sealer specifications, but most commercial impulse sealers are compatible with 6 mil poly tubing.
What products benefit most from light-blocking black poly?
Pharmaceuticals, vitamins, photo-sensitive chemicals, UV-sensitive electronics, and food products requiring light protection all perform better in opaque black poly tubing compared to clear alternatives.
